GOMIARTMENT SURFACE QONIFENSER.

To all whom it may concern:

Be it known that I, PAUL A. BANCEL, a citizen of the UnitedStates, and aresident of Nutley, county of Essex, State of New Jersey, have inventedcertain new and useful Improvements in Compartment Surface Condensers,of which the following is a spec fication.

This invention relates to a compartment surface condenser and theprimary object of the invention is to enable the different compartmentsto be readily cleaned as desired, while the condenser is in operation.Another object of the invention is to reduce the pumping power and costin winter, by reducing the water quantity due to the fact that the wateris colder and therefore less water is required.

To these and other ends hereinafter to appear, the-invention consists ofthe condenser shown in one of its preferred forms in the accompanyingdrawings, in which Figure 1 is a side elevation of a condenser embodyingthe invention,

Figure 2 is a transverse sectional elevation on the line 22 of Figure 1,taken through the inlet water box, looking in the direction of thearrows, and partly broken away,

. Figure 3 is a transverse sectional elevation on the line 3--3 ofFigure 1, taken through the outlet water box, looking in the directionof the arrows, and partly broken away.

Referring to the drawings, the shell A of the condenser having suitabletubes and tube sheets is provided with the steam inlet B,

and the outlet connection C to which the cooler D is connected in thisinstance, 'having the water, inlet E, the water outlet F and the vacuumpump connection G.

The shell .A is provided with the inlet water box H at one end, to whichthe outlet Specification of Letters Patent. Patented Feb, 14, 1922Application filed November 9, 1920. Serial No. 422,797.

sages S having the covers T so that communica-tion may be affordedbetween two of y the lower compartments.- Water inlet valves U and Vcontrol the supply of water to the water inlet box and discharge valvesW and X control the discharge of water from the water outlet box. A mainvalve Y on the supply connection E of the cooler also discharge pipe 0controls the discharge from the lower portion of said box. Thecompartments are provided with the remov-, able cover end.

In Isummer, or at such times when the full capacity of water inlet isutilized, the covers T on the partitions R are in position and eachwater box is divided in this instance into three compartments,'so thatwith all the valves open, the circulation of water is through the inletvalves U and V, the upper compartments: of the inlet box and :outthrough the discharge valves W and X. The circulation is also throughthe inlet valve Y, thence through the cooler and into the lowercompartment of the inlet water box and out. through the discharge valveZ to the discharge pipe 0.

In the winter, by operating a large eondenser with most of the waterforced through the valve U and the upper compart ments having the widetube spacing, a high vacuum can be carried with small loss of pressurethrough the condenser and small reduc tion in temperature of the steam.This condition is effected. by throttling the inlet valves V and Y orelse by closing the inlet valve V and removing the cover plates T on thepartitions R, and throttling the inlet valve in which case thecirculation is through the cooler- D and the discharge pipe J to thelower inlet compartment and through the passages S'in the partition R tothe intermediate inlet compartment and thence to the final dischargethrough the valves X and Z, from the intermediate :and lowercompartments of the outlet box. Under these conditions the greaterportion of the steam will be condensed in the top of the condenser, sothat the temperature of the bottom of the condenser will be near thetemperature of the top. In the usual commer- 70, plates at, b ar d c asshown at each in the same way.

the valves are closed'except the inlet and cial'condenser the condensatemay run 20 cooler in winter than the steam temperature and this meansfrom 19 to 2% loss of coal in'the plant, or a loss the equivalent ofonefoui' th inch in vacuum from the main turbine, and in accordance withmy apparatus, 1 am enabled to save a substantial percentage of thisloss.

Under winter conditions, or with light load, in case it is desired torun with less ,water and with normal vacuum, instead of eihg nsualamount of water and a higher vacuum, this-may be done, with the samevalve setting above described andthe cover plates T removed.

' By closin -the inlet and discharge valves U and W, t e top compartmentcover plates (1 may be removed and the tubes communieating with theuppercompartments cleaned while the condenser is still running with allother valves open. By closing the inlet and discharge valves V and X andleaving the other valves open, the intermediate cover lates b may beremoved and the intermediate tubes cleaned. By closing the inlet anddischarge valves Y and Z, the cover plates 0 for the lower compartmentmay be removed and the lower tubes cleaned.

B closing all valves except the inlet and discharge valves U and W, thewater can be forced through the tubes communicating with the topcompartments at very high velocity, thus cleaning said tubes, and byclosing all the valves except the inlet and discharge valves V and X,the tubes of the intermediate compartments can be cleaned In the samemanner if all discharge valves -Y and Z, the water can be forced throughthe tubes for the lower compartments at high velocity for cleaning saidtubes and the ability to clean the tubes for any given compartment byforcing water at a high velocity through them, is another one of theadvantages of my apparatus.

I claim:

1. Asurface condenser comprising a shell having tubes, water inlet anddischarge boxes at each end of the shell divided into oppositecompartments by horizontal partitions, the lower partition havingpassages and closing covers for said passages, sep arate removablecovers for said compart- 'ments, an inlet pipe for the inlet box, a

discharge pipe for the discharge box, and inlet and discharge valves foreach of said compartments.

2. A surface condenser comprising a shell having tubes, water inlet anddischarge boxes at each end of the shell divided into oppositecompartments by horizontal partitions, the lower partition havingpassages and closing covers for said passages, separate removable coversfor said compartments, an inlet pipe for the inlet box, a discharge pipefor the discharge box, a

cooler connected to the condenser having an inlet for water and a vacuumpump connection, the water discharge of said cooler being connected tothe lower compartment of the'inlet box, and inlet and discharge valvesfor each of said compartments.

In testimony whereof I have signed this specification.

PAUL A. BANCEL.
